Abstract
A guide rail and sliding block mechanism used for support moving and arranged on a top beam of a hydraulic support comprises a guide rail sliding face, a guide rail section contour, a sliding block matched with guide rails and fit clearances of the guide rails and the sliding block. The guide rail and sliding block mechanism is characterized in that the fit clearances of the guide rails and the sliding block are changing, and transitional faces are arranged between the sections, where the fit clearances are large, of the guide rails and the sections, where the fit clearances are small, of the guide rails. After the structure is adopted, the sliding block can keep large clearances in the sliding process to enable sliding to be smooth, when the sliding block is about to reach the end point, the fit clearances are small or even eliminated, so that the top beam has high locating precision automatically before supporting a top plate tightly, therefore, the work load of support adjusting is reduced and the yield is increased. The guide rail and sliding block mechanism is particularly suitable for control over support moving of sliding supports, chain suspension type supports, combined supports and the like.

Utility model content
The purpose of this utility model is to provide on a kind of hydraulic support top beam for moving the guide rail slide block mechanism of frame, hydraulic support is installed after this guide rail can be laborsaving, advance quickly, and not only can avoid breaking bad slide block, and workload that can less tune frame, output improved.In order to address the above problem, on a kind of hydraulic support top beam of the utility model, comprise guide rail slide plane for the guide rail slide block mechanism that moves frame, guide rail profiled outline, the gap that the slide block coordinating with guide rail and guide rail coordinate with slide block, the fit clearance that it is characterized in that guide rail and slide block changes, and between and each section of guide rail that gap is little large in gap, is provided with excessive face.
On hydraulic support top beam, for moving a guide rail slide block mechanism for frame, it is characterized in that described guide rail is female surface, slide block is inclusive between guide rail, is provided with the variable cross-section section that part narrows on guide rail.
On hydraulic support top beam, for moving a guide rail slide block mechanism for frame, it is characterized in that described guide rail is male surface, slide block wraps in the outside of guide rail, is provided with at guide rail the variable cross-section section that part broadens.
On hydraulic support top beam, for moving a guide rail slide block mechanism for frame, it is characterized in that described guide rail is with the little gradient of the large other end size of one end size.
On hydraulic support top beam, for moving a guide rail slide block mechanism for frame, it is characterized in that described guide rail slide block mechanism is provided with the structure to slide block location in addition while sliding into local location.
Adopt after such structure, just can make slide block maintain larger gap in the process of sliding, make slide block smooth and easy, and gap is less in the time that slide block will reach stroke end, eliminate even, make back timber there is automatically higher positioning precision before stretching top, thereby reduce the workload of adjusting frame, increase output, so the beneficial effects of the utility model are obvious.
